> "U2" has a concert that starts in 17 minutes and they must all cross a bridge to get there. All men begin on the same side of the bridge. You must help them across to the other side. It is night. There is one flashlight. A maximum of two people can cross at one time. Any party who crosses, either 1 or 2 people, must have the flashlight with them. The flashlight must be walked back and forth, it cannot be thrown, etc. Each band member walks at a different speed. A pair must walk together at the rate of the slower man's pace:

Huh! I've done it! I've really done it!

First. Bono and Edge. 2 min.
Second. Bono returns. 1 min, sum 3 min.
Third. Adam and Larry. 10 min, sum 13 min.
Fourth. Edge returns. 2 min, sum 15 min.
Fifth. Bono and Edge. 2 min, sum -- **17 min**!!!

by the way, that's interesting for me, doesn't it take time to get to the place of the concert from the bridge? ;-)

Nor "maybe i should go working to MicroSoft?" kuin
